PROBLEM TO BE SOLVED: To provide a vehicle skeleton structure capable of joining four or more plate materials without deterioration of rigidity.SOLUTION: All six panels comprising a weld part 46B of a side member outer panel 46, a front flange part 40B of a pillar outer reinforcement 40, an upper flange part 28B of a locker outer panel 28, an end 34A of a partition wall panel 34, an upper flange part 30B of a locker inner panel 30, and a front flange part 42B of a pillar inner reinforcement 42 are welded (joined) by laser welding (LSW) at a same position at ends of the six panels on a rear part and a lower part in an inner edge of a front side door opening 24 side (a laser welding part 48). In LSW, four or more plate materials can be welded, therefore it is not necessary to form a notch or a hole on the laser welding part 48. Therefore, the plate materials can be joined while securing rigidity. |
